JOSEPH C. SPARROW, OF CLEVELAND, OHIO.

VAULT-DOGR.

To all 'whom it may concern:

Beit known that l, J osnrn O. Srannow, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a new and useful Improvement in Vault-Boers, of which the following is a specification.

My invention relates to improvements in iire prooi vaults and doors, and the object of my invention is to provide a simple and efficient method of constructing a lire prooiI vault door', and connecting it with the vault so that no opening will remain for the entrance of lire, air or water, and further to provide a simple and inexpensive iireproof door.

My invention is illustrated in the accompanying drawings in whichw Figure 1 is a vertical sectional view of a vault wall and door. Fig. 2 is a horizontal sectional view of the vault and door.

ln the drawings A represents the Walls of a lire proof vault, having an opening for the vault door, and B represents the vault door. rlhe walls may be made ci hollow tile or reinforced concrete or other fireprooi ma terial. Fitting into the door opening in the fire prooi` wall A, is a back door 'frame O, and a iront door frame D. The trames C and l) are preferably made of angle iron, the outer sections of the iron engaging the wall to which it is attached and the inner sections inclosing the wall at the door opening.

Attached to the inner Jface of the frames O and l), are plates E E E which serve to hold the frames C and D in position to the wall and which entirely inclose the wall from view at the opening on the sides and the top of the opening.

At the bottom oi the door opening is a plate F, preferably made ot metal over which is placed a sheet G, of asbestos or other tire prooi` material, and over the sheet G, is placed a covering H to protect the asbestos sheet G.

Attached to the front vault opening is a 'further trame J to which is attached the vault door hinges l. The vault door consists or" a iront door plate K, preferably made of steel. The door plate at its sides and top laps over the door frame D, and at its bottom it is adapted to tit closely to the top oi the plate F, and when the door is closed the plate K rests in contact with the asbestos plate G. Attached to the door plate K is a Specification of Letters atent.

Serial No. 424,823.

the 'frame L is a plate ot asbestos m. The sides and top ci the door thus formed when closed, iit closely up to a further asbestos plate n, which is attached to the plate E.

ln the manner shown is provided a cheap` and simple iire prooi door construction. The iront door plate overlaps the space between the door and the wall, and engages the asbestos plate G, thus entirely closing the opening in the iront and the asbestos plate m further closes the rear oi the opening between the door and wall.

In the construction shown the outer door plate K and asbestos plate m, are so located as to form an air space which lprevents the heat from penetrating through the door, and thus providing all of the protection afforded by two separate doors. rl`he door is provided with bolts to lock the same but the form or construction of the same is not material to my invention. Other ireproof materials may, if desired, be substituted for the asbestos described.

What l claim as my invention and desire to secure by Letters Patent, is,

1. In combination, a vault door consisting of an outer plate, a frame attached to the same and an inner plate of tire proof material attached to the frame, said plates so located as to form an air s ace between the saine, a frame attached to t 1e vault opening and having a plate of fire proof material attached to the same and adapted to engage the vault door when closed, substantially as shown and described.

2. ln combination, a vault door having an outer plate connected by hinges to the side of the vault opening and overlapping the sides and top of the vault opening, an asbestos plate engaging the outer plate at the bottom of the opening, a frame attached to the outer plate, and an inner asbestos plate attached to the frame, said inner and outer plates so located as to form an air space between the saine, substantially as shown and described.

3. ln combination, a vault door consisting of an outer plate, a frame attached to the same and an inner plate of asbestos attached to the frame, said plates so located as to form an air space between the same, a frame attached to the vault opening and having an asbestos plate attached to the same vand adapted to engage the vault door when closed, substantially as shown and described.

4. ln a vault, in combination, a vault wall further angle iron frame L and attached to having a door opening, angle iron frames attached to the Wall at the opening, a connecting plate attached to the frames at the Vault opening, a vault door connected to the Wall and adapted toclose said opening and consisting ot an outer plate connected to the Wall a frame attached to the plate and a plate of asbestos attached to the frame, and an asbestos plate attached to the connecting plate and engaging the edge of the door When closed, substantially as shown and described.

5. ln a vault, in combination, a Vault Wall having a door opening, angle iron frames attached to the Wall and a metallic connecting` plate attached to the frames, a Vault dooi` suitably connected to the Walls by hinges and adapted to close said opening and consisting of an outer plate overlapping the opening at its side and top and engaging an asbestos plate at the bottom, a frame attached to the plate and a plate of asbestos attached to the frame and an asbestos plate attached to the connecting plate and engaging the edge of the door When closed, substantially as shown and desciibed.

In testimony whereof I have signed my name to this speciiication in the presence of two subscribing witnesses.
